Mein Auto: 99 M Coupe
These posts helped me do the CCV (only) on my 99 M Coupe (S52) in about 45 minutes. My task may have been simpler than others because of model differences, but here is what I did.

I bought a 10mm ratcheting box end from Sears...

Removed the air filter box.

Removed the crankcase vent pipe (to CCV).

Removed the vent tube from the lower connection leading to the dipstick tube.

Loosened one hose clamp to give access to the first of the three 10mm bolts holding the CCV on its bracket.

Removed the 3 10mm bolts (thank you, Sears), then removed the CCV...snaking it forward over the alternator into the space made available by removing the air filter box. Minor maneuvering required.

I then attached the new vent tube to the bottom of the new CCV and installed them (after inserting a new rubber grommet to the underside of the intake manifold). The 3 10mm bolts installed easily with the ratcheting box end.

Attached the vent tube to the dipstick tube. Attached the crankcase vent pipe. Tightened the hose clamp. Installed the air filter box.

Done in 45 minutes. No misadventures in this case, though far more limited in scope than the above project(s).

Hope it helps.
